The success of demand management approaches to curbing flight delays is predicated on an accurate and reliable a-priori determination of airport arrival and departure capacity. The assignment of declared capacity, completed more than one year in advance, must consider the inherent variability in the actual throughput capacity for each 15 minute period during the day. For airports with large variations...
In this paper, we study the time-optimal trajectory planning of a sensor attached to an unmanned aerial vehicle (UAV) to provide complete 3-dimensional coverage with applications to urban environments with 2.5-dimensional features. The basic approach is to approximate the features of interest with a set of non planar coverage surfaces and to design a motion plan that guarantees the coverage surface...
In this paper, we present a scalable, decentralized task allocation algorithm for a group of unknown number of unmanned aerial vehicles (UAVs), which are equipped with GPS receivers, synchronized clocks and radars with a finite, but known operating distance to identify neighbors. The algorithm assigns subgroups of UAVs, whose initial positions are randomly scattered in a bounded space, to a finite...
In today's modern supersonic aircrafts, a split of seconds decision is required from pilot in coping with the continual eye adjustments for focus, brightness of symbology displayed, the line of sight between various displays of cockpit and the outside world. Many avionics display systems have been designed throughout the world. Head-Up-Display (HUD) is one of the important and critical systems in...
Unmanned aerial vehicles (UAV) can be used to cover large areas searching for targets. However, sensors on UAVs are typically limited in their accuracy of localization of targets on the ground. On the other hand, unmanned ground vehicles (UGV) can be deployed to accurately locate ground targets, but they have the disadvantage of not being able to move rapidly or see through such obstacles as buildings...
